The complete chloroplast genome of Hook. f. et Thoms. ex Benth. was sequenced and analyzed. The circular cp genome of is 162,642 bp in length, consisting of inverted repeats (IRs; 26,437 bp), small single-copy (SSC; 18,762 bp), and large single-copy regions (LSC; 91,006 bp). The genome contains 131 genes (86 protein-coding, 37 tRNA, 8 rRNA) with 37.0% GC content. Phylogenetic analysis revealed the monophyly of Stachyuraceae, and was sister to the other 3 species examined. Our results provide useful genetic resources for further studies on the evolution and phylogeny of Stachyuraceae.
对Hook. f. et Thoms. ex Benth.的完整叶绿体基因组进行了测序和分析。其环状叶绿体基因组长度为162,642 bp，由反向重复序列（IRs；26,437 bp）、小单拷贝区（SSC；18,762 bp）和大单拷贝区（LSC；91,006 bp）组成。该基因组包含131个基因（86个蛋白质编码基因、37个tRNA基因、8个rRNA基因），GC含量为37.0%。系统发育分析揭示了旌节花科的单系性，且该物种是所研究的其他3个物种的姐妹种。我们的结果为旌节花科的进化和系统发育的进一步研究提供了有用的遗传资源。
